My invention further relates to means for preventing lon il'noimlmovement of the rolls... to the provision oi. suitable fixed and movableui lo rolls. to insure theprmluction oi a wvtevt ring; to theprovisionof adequate means for supporting and moving the movable roll; to thoconstruct on of the rolls thcumolvesi; to the prov sion of adjustingmeans or stop or lien-1' wining the awn-oi of k semi inn.

aceessto the rollers for the'roller system; and. a

relative movement of the rolls, and to other features of constructionanti arrangement which Will more definitely appear from the followingdescription and claims.

In the appended drawings. which represent a preferred embodiment ofinvention,'

Figure 1 is a view in elevation;

Fig. 2 is an end view from the left in 3 Fig. 1;

F lg. 4 a vertical transverse section on the line ieit, 1;

Fig. 5 a vertical longitudinal section on the line Fig. 4.;

6 a vertical transverse section through an end view from the right inroll and is turned. about an axis which is fixed relatively to theframe.

The shattS which forms the outer roll or carries a separate roll ismounted in a %ii t able frame 9 normally above the roll 6 so that, thedistance between the rolls may be varied as the thickness of thematerial pressed hetween them fliminishes.

The shiftahle frame 9, which forms a material part of my invention,comprises a cross-web 10 carrying journal-boxes 11 and 5 12,respectively, at its ends. The journalboxes have cylindrical surfaces toslide along; the walls of curved openings 13 and 14, in the uprightframes 1' and 2. To form. an extended guide for these journal-boxes, theframes 1 and 2 are formed with flanges i and 16., respectively; Thejournal-boxes 1 and 12 are preferably made iii separate pieces andattached to the cross-web 10 in any suitable manner. as by bolts 17. itis thus seen that the frame 9 and with it, shaft 8, can be shifiedtoward and away from the shaft 6 for the purpose above specified.

The cross-web is designed as tively brace the shaft or roll. 8 againstbending stress. To properly limit the space be tween rolls 6 and 8 andthus determine the thickness of the ring to be pressed, l have providedadjustable stops. As a convenient means for that purpose I have shownbolts 15 and 16, as best shown in These bolts extend from the unilersideofflanges l4 upwardly through the bem'ingliloclrs 7, i of the roller 6.Normally, they are at their upper cud Hush with the upper face of theseboaring-blocks. llhen it desired, however, to space the rolls 6 and 8for a greater thick ness of the hoop. the bolts are advanced so thatthey protrude above the surf. cc of the bearing blocks 7', 7. a requiredamount. For the purpose of adjustment the bolts are provided with asmooth portion 13 and a. s :IcW iillI'QtHlPil pol'ijlflllx il adapted toengage a scrmv-tln'czu'l in the flanges 14-. A lock-nut 17" is prorii.al for each bolt to secure the bolts in adjusted position. These stopsare importa at, as by their proper adj ustmcnt. the pressure rolling ofthe blank is stopped just at such time as the outer periphery of thefinished ring, IOOQas shown in Fig. 6, comes into engagement with theguide rolls. Dis tortion of the ring is thus prevented and theproduction of a perfect ring insured.

While any suitable mechanism may be resorted to for operating thejournalcarrying frame 9, I have shown as a? preferred fern-i of suchmechanism a lever 18 fulcrumiui on a shaft 19,--whicl1 will be moreparticularly referred to bclow,--said lever haying a short arm 20connected to the crosswch 10 and its longer arm connect-mi to a sourceof pressure This source of pressure is pnxferalily a hydraulic engine.but its spccil'l form in immaterial and does not form a. part of my in--vention. It has the fimction of t shaft 8 towzird the shaft 6 andsupplying the power necessary for the rolling procc It is understoodthat there are means, as customacv. for relcasuiu;- the pressure atwill. This feature is not illustrated, since it is well understood. Thelever 18 is preferably mounted on shaft 19 by means of a. dividedhearing, as clearly shown in dotted lines in Fig. 4, so that the levercan be attached and detached without disturbing other parts of theapparatus.

The shaft .19 is supported at its ends in the upright end portions 1 andof the frame in such a manner that the wear is taken. up principally byhearing caps 93" and 9.1. For this purpose the in a 21 and 2).. a'sisseen in Figs. 2 and '3. cml'srace the nutjor part of the lower bearingthe wear becomes excessive, i re ilacecl by to eii'ec- 23 of the frame,

iln-ough gears a new cap with little expense, while the frame itself islittle affected. The caps are held in position by bolts 19 and by arms22" which are in. turn clam )ed in a bifurcation as by olts 90. Thisform of mountinq makes it possible to take out shaft 19, wien desired,and to give access to tl interior of the machine for purpose of repair.I

For the power transmission for turning the shafts (l and 8 and thermviththe rolls.

have designed a simple set of gears and the particular arrangement-formsan. im port-ant part of my invention.

1e frame presents at its left-hand edge (see Fig. 2) a, substantiallyvertical wall. This wall is shaped to form three half bearings 23, 24:and The other half for these hearings is provided in the form ofdetachable caps 26, 27 and 28 (see Fig. 6). bearings are identical oneach of the upright end portions 1 and 2 and accommodate shaft-s 29, 30and 31.

Slmft 29 carries a fly-wheel pulley 32 for a belt :lrixc and a pinion33. This pinlmi, meshes with a gear 34 on shaft 30, see Fig.

1-. On shaft 30 are two pinions 35 and 36' to transmit the power fromshaft 30 to shaft through gears 37 and 38. Gears 3} and 38 in turn meshwith gear-teeth 39 and 4:0, respectively, on shaft 6, as best shown inFi 4 and 5.

The gear-teeth 39 out directly into the is an important feature, sinceit reduces the distance between the shafts or rolls 6 and 8 to a minimumand thus makes it possible to roll exceedingly thin rings between therolls proper. It is of course possible to reduce the distance betweenthe rolling surfaces to any small amount desired by providin rollerslarger in diameter than rolls 6 and 8, but I have found that theincrease of the rollers in diameter is not desirable. since they have atenrlenov. due to their high circumferential speed, to tear and dis--rupt the fibers and texture of the material of the ring. I have avoidedi'lis iliiiii-ulty by reducing the distance between the aha-Firs orrolls to the smallest possible amount From shaft 31 the power is alsotransmitted to shaft 8 through a gear 41 at the end of shaft 31 whichprojects outside the frame port-ion l, the gear 41 meshing with a gearkeyed to shaft 19 (see Fig. 3) and 43 and 44 on shaft 19 cugaging gearteeth 45 and 46, respectively. on sl'iaft'8. It will be noted that thesegears +15, 46 are located close to the bearings, and that the bearingsare relatively long, so that transver:.-1e and torsional strains arecounter noted. The location of the cars 45, 4.6 in the shaft. enablesthe shafts to be made very strong and of substantially the same the shaor amiable-aim in ill qn'odueet-l on the ed eter. There very littletendency for lateral or side-Wise metal-flew. thott-he Width of the ringremains substun ully the some. Any slight irregnlmiifies whit-h tend 'tohe s or the rings are how-- ever prevented by the 1. that the ring us itis rolled is kept with its unis purullel to the axis of the rolls,beeuusr of .ihe faret that its edges bear against; the plates (5:5 and70, which also prevent any sidewise Web tiling of the ring being rolled.llhe massive structure of the standard and the support 2-, together withthe mnple bearings afforded for both ends, and pmrtieuhn'ly the outerends of each of the rollers insure he pro duction of a substuutiallyperfect ring with its inner and outer faces in puredelism.

It will be notel'l that the upper roll 51 is slightly larger in diameterthan the loud-n. roll 52 end. this feature purp at zulopted, it?? it hasbeen foun that it slightly greater eircumfertmti:rl L l of the outer ior pressure roll (muses more ell'ectire and uniform distribution of themetal.

It "will also be noted that in my muehme the press-n1 1s applied to theoutside roll and this is done for the reason that'I have found inpractice. that a greatly superior resul t is obtained by thisarm.s'igemem'.

' While I have Sl'lOWIl a machine adapted for rolling u plain. orpm'ellehsided ring, it is obvious that many other forms may be rolled,by suitable changes in configuration of the rolls. Exumples'of suehforms are shown in Figs. 1-11.
